It's interesting everyone's take on farming.
Most everything I've read suggests bouncing back from Ezra to Hera on farm, but Ezra first. I did the opposite, mostly because Hera can put auto-revive on anyone but herself. She really doesn't have enough health & I thought the extra star did her good. Yes, you sacrifice a small amount of offense with Ezra trailing, but no so much in the early stages of the game and losing Hera sucks.
anyway, I'm not saying I'm right & everyone else is wrong, I'm just saying I did it different and it worked for me.
